Flat litz wire 7.4mmx7.4mm Kapton 0.071mmx6500 Taped Litz Wire For High Frequency high Voltage applications
Engineered for the most demanding power electronics applications, our Flat Taped Litz Wire combines precision stranding with high-performance insulation to deliver superior efficiency, reliability, and safety. This specialized wire is constructed from 6,500 individual strands of 0.071 mm enameled copper wire, stranded together to form a flexible, high-density conductor. The fine-strand construction effectively mitigates skin and proximity effects, significantly reducing AC losses at high frequencies—a critical requirement for modern transformer and inductor designs.
·IEC 60317-23
·NEMA MW 77-C
·customized according to customer requirements.
The finished litz wire is wrapped with a robust layer of Kapton polyimide tape insulation, providing exceptional thermal stability, chemical resistance, and dielectric strength. With this insulation system, the wire is rated to withstand minimum test voltages of 6,000 volts, making it ideally suited for high-voltage applications where insulation integrity is paramount. The overall cross-section measures 7.4 mm × 7.4 mm, classifying it as a larger-profile litz wire capable of handling substantial power levels while maintaining a compact form factor for space-constrained assemblies.
This flat taped litz wire is specifically designed for high-frequency transformers, grid-tied inductors, solid-state transformers, and high-power conversion systems. Its typical applications span renewable energy inverters (solar and wind), electric vehicle charging infrastructure, aerospace power supplies, industrial welding equipment, and traction systems for rail and heavy-duty vehicles. The combination of high strand count, precision flat geometry, and high-voltage-rated Kapton tape insulation offers engineers a reliable, ready-to-use solution that simplifies winding processes, improves thermal management, and ensures long-term durability under extreme electrical and thermal stress.
Whether you are designing for next-generation power grids or rugged industrial environments, this flat taped litz wire delivers the performance and safety margins your applications demand.
